Looking at the extremely hidden passageway on the ground, Mao Jiamin couldn't help but feel aroused in his heart. Fortunately, with Zhao Yue's guidance, otherwise they would definitely not be able to find this entrance alone.

"I'll go down first, you guys follow me." A very long rope was pulled out from the tool kit behind Wei Dayong, and then threw it down. It seemed that the passage was not very deep.

Immediately afterwards, Mao Jiamin pulled the rope with both hands and began to fall into the passage. Not long after, his feet were already on the ground. "It seems that this safety was built in a hurry, and I don't know if it is a refuge."

After the great Yong Zuoran and Zhao Yue both landed one after another, they turned on the flashlight and the dark environment around them was illuminated instantly. There was an endless corridor in front of them, and there was no end at all.

There were many strange handwriting on the surrounding walls, many of which were not men, which also made the four of them dizzy.

"Brother Jiamin, why do I feel that this place doesn't look like a safety center, it's like an alien base played on TV!" Wei Dayong watched everywhere, while talking about the alien movies he had watched.

As we walked along the way, we could see a slight light ahead. "Look, there should be a lot of people there." Zuoran pointed to the front and said.

As soon as he came in, Mao Jiamin realized something was wrong. Until now, he finally confirmed this theory, "It seems that this is not a safety place, we were cheated."

"Don't go there first, they don't seem to have found us yet." The four of them carefully concealed their bodies as much as possible.

"Brother Jiamin, what are they holding in their hands." "Is that... a gun? It looks very similar."

Because of the first layer of the secret, Mao Jiamin's vision has also been slightly improved, and it is clear that there are no less than ten people standing at the entrance of the passage.

And everyone is holding a new weapon in their hands, which looks like a machine gun. This is all the information Mao Jiamin can learn at the moment.

"Zhao Yue, have you remembered anything now?" The three of them looked at Zhao Yue, who was full of panic on their side.

"It seems... very familiar here. The group of people in front are holding biological and chemical weapons!" "It is a powerful weapon that can easily defeat ordinary zombies, and it is also very effective against humans."

"But the cost is very expensive, and it seems that the material is rare." Zhao Yue thought hard, and at the same time said everything he had thought of.

"Biochemical weapons, the first time I heard of this kind of thing." Mao Jiamin thought about it, but he had never heard of any news about biochemical weapons before.

"There must be any conspiracy here. Do you want to go in and take a look?" Mao Jiamin looked at the three of them with interest and asked.

Wei Dayong and Zuoran both nodded in agreement, only Zhao Yue looked hesitant, but when he saw the innocent expressions of the three of them, the uneasiness and anxiety in his heart disappeared, replaced by an incomparable sense of happiness.

"Make a plan so as not to alarm the snake." Zuoran came over in the direction of Mao Jiamin and said.

"It may be difficult to find a way to get rid of the ten people in front. We are not clear about the function of the biological and chemical weapons in their hands. Are there no other aisles here?" he looked at Zhao Yue and asked.

Mao Jiamin subconsciously asked Zhao Yue Xiao Loli about all the questions here, but the little loli has not disappointed everyone again, and this time is no exception: "Yes, I remember that there is a passage leading to the upper floor not far ahead, but you have to stand up to get there."

"And it must be done without disturbing them." Zuoran reminded that this is undoubtedly a very difficult action. To avoid being discovered by them, there are many difficulties, luck, and also requires exquisite control of time.

"After going up, you can go down from the exit. There will definitely be no guards there. After all, it is at a high altitude and there is no way for people to do it." Zhao Yue looked at Mao Jiamin with a worried look on his face and said.

"Okay, I want to seize the opportunity. Look at their actions, they are very regular. They will walk back and forth every thirty seconds. During the walk, their eyes will not look at the channel. The time for each walk is about thirty seconds. In addition, they keep staring in the channel. They can only take these thirty seconds to move." Mao Jiamin observed carefully again, firmly believing in the results he observed.

After thirty seconds, after a while, as Mao Jiamin expected, the group of people opposite began to move, and Mao Jiamin also moved, her body hidden in the darkness, crawled and quickly arrived at the designated position, which took about twenty seconds.

With only ten seconds left, Mao Jiamin did not dare to delay at all. He quickly stood up and exerted force on his legs. He jumped up and jumped up. He clasped his hands tightly on the ground on the ground and pulled his body up.

Mao Jiamin only took twenty-nine seconds to complete the whole process. Thirty seconds later, the group of people began to stare at the inside of the passage again. At the moment when Mao Jiamin was about to jump on, he couldn't help feeling relieved.

Zuoran and the other two were also worried about Mao Jia. This was just the beginning. It was the most difficult thing to solve the ten-person team.

Slowly crawling forward, Mao Jiamin deliberately lowered his breathing sound. He always felt that these ten people were not angry at all, as if they were a soulless shell.

After reaching the top, you can clearly see everything below, and it is still a expressionless person patrolling, without the fatigue or any feelings that humans should have.

What Mao Jiamin had to do next was to jump from here and quickly wipe out these ten people with a fruit knife. This was almost difficult to do, but after understanding the first level of the secret, Mao Jiamin was sure that he could take a try.

These people seem to never be tired and still maintain the routine of moving in thirty seconds. If they want to deal with them and not alert the enemy, they can only assassinate, but Mao Jiamin does not have the weapons needed for assassination.

"Wait, I seem to have a gun!" Suddenly, a bold idea rang out in my mind, and I touched my waist. Sure enough, a small black exquisite pistol appeared in my hand.

This was given to him by Zuoran. Because the power is very small and it takes a close distance to kill the enemy, it also leads to a small sound. With the silencer, there is almost no sound.

He quickly installed the silencer and Mao Jiamin licked his chapped lips and said, "It's finally my turn to use a ranged weapon this time."

A gunshot that was almost silent was sound, and then the last person walking on the patrol below fell quietly to the ground, and the remaining nine people were instantly alert.
